Hash House online coupon request for clarification

The online coupon for hash House a Go Go states 25% off your bill. The terms and conditions say 15% off food only. 

Is it 25% off or 15% off? Is it off the full bill or only the food? 

I presume one of these was a typo but not sure which one. 

Thank you. 

Sorry about that. There are 2 coupons, one for 15% and one for 25%. The 25% one is for platinum members only. Both are for food only. 

Thank you
